Abstract

The invention discloses a method and an apparatus in a node for wireless communication. The node receives the first information; receives a first signaling; sends the first signal. Tthe first information is used for determining a first characteristic parameter group, the first signaling is used for determining a target time length from a first time length set, and the first characteristic parameter group comprises at least one of the type of a sender of the first information, the height of the sender of the first information and public time migration; the first time length set is an alternative time length set in X alternative time length sets; the first characteristic parameter group is used for determining the first time length set from the X alternative time length sets; the target time length and the common time offset are jointly used for determining the time interval length between the receiving moment of the first signaling and the sending moment of the first signal. The present application ensures successful uplink transmission.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission scheme and device with a large delay in wireless communication. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) (or 5G) research, passed the WI (Work Item, work item) of the new air interface technology (NR, New Radio) at the 3GPP RAN#75 plenary meeting, and started to standardize NR. [0003] In order to adapt to various application scenarios and meet different needs, the 3GPP RAN#75 plenary meeting also passed the research project of non-terrestrial networks (NTN, Non-Terrestrial Networks) under...
